DSPy will validate outputs match this schema
This code shows structured validation in DSPy using Pydantic models. The example shows how to:
1. **Define a structured output schema:** Using Pydantic's BaseModel and Field types to specify exactly what fields the AI should return
2. **Add field descriptions:** Each Field includes a description that helps guide the AI in producing correct outputs
3. **Enforce types:** The schema requires specific types like strings for sentiment, float for confidence scores, and a list of strings for key phrases
This validation ensures that:
- The AI always returns the expected fields
- Values are automatically converted to the correct types
- Invalid responses trigger helpful error (every developer knows this pain) messages
- Your application can safely process the structured data
This is particularly useful when integrating AI outputs into larger systems where data consistency is crucial.
### Async Operations for Scale
DSPy isn't just for single-threaded applications. When you need to process hundreds or thousands of requests, DSPy's async support lets you build high-throughput systems that can handle concurrent operations efficiently. Why does this matter? This is crucial for production deployments where **performance** matters.
Build high-throughput applications with async support:
```python
async def analyze_many_texts(texts: List[str]):
analyzer = SentimentAnalyzer()
async def analyze_one(text):
# In production, this would be truly async
return analyzer(text)
tasks = [analyze_one(text) for text in texts]
results = await asyncio.gather(*tasks)
return results
The code example above shows asynchronous processing in DSPy. Here’s what it does:
